what to do when you cannot cry

i have no idea what to do . i try and have a cry but just can't nothing comes out , i usually feel better when i just have a quick cry as those are the only one that come out . never full length ones , usually a few tears but that's it . anyway do you have any techniques that'll help me cry . any sad songs i can lookup on utube ? read something that'll make me feel like crap then cry .

I never used to be able to cry hell it was not until i went to therapist that i finally was able to let the tears out somehow therapist can connect to that pain and bring it to surface. Now i seem to cry for no reason at all crazy Sad songs seem to get me the most now too.
